`This invention relates to improvements in carbonating machines Vfor themanufacturing of carbonated water.` i 1 .1 Heretofore, machines of this" character have been provided. with a mixing tank in which gas and watervareintroduce'd and agitated by the action of a rotatable agitator, the same being turnable `in one direction only and which Vdoes not thoroughly mix the.carbonated gas and water, while we aim to im# part reverse rotation4 to'the `agitator to assure a thorough mixing of the elements under comparatively low pressure. l

1 Another object of the `invention is to pro` vide VVa carbonating machine' injwhich` the cally `controls the pumping of water tothe tank, butwhich does not interferewith the voperation ofthe agitator, although both the pump andthe agitatorreceive their power romafcommon source.` i. lA` further Vobject is to Veliminate the use of rubber hose `between the liquid levelconi 5o machine...` l i trolling vessel and the connection withfthe source of liquid supply, as ithas been proven thatby `,reason of constant lflexure of the hose, the same tends to weaken. and also the passageof Vwater therethrough induces de.- terioration and unpleasant odors which might contaminate the carbonated kwater produced by the machine. i i f A still further object is to Vprovidefa care bonating machine which istsimplexof construction', automatic `in operation, and strongand durable for the purpose intended.

With :these and other. objects in view, the invention resides inthe certain novel construction, combination andarrangement of parts, theessential features of which are hereinafter fully described, `are particularly pointed outinthe appendedgclaimgand are illustrated in the accompanying drawings, in `whichz` i i i 4Figure 1 is affront elevational view of our i `improved lcarbonating machine.

L The meeting ends of the two tank sections 26 and 27 are provided withlianges `29 l"andl ,30,'respectively; which are iiXedly connected, together bya plurality joffbolts or like fastening elements V31. y

The numeral 33 designates a double acting water pump bestshown` in Figures l and 3 of the drawings, and which pump is operableby a double acting crank 34: as best seeninFigure lof the drawings. Axially alined crank shafts and 36 ,are mounted in bearings `atthe top of the frame 23,' while a crank pin 37 isl iixedly'connected tothe crankarms 38 and 39 respectively connected to the crank shafts B5' and 36.' Thebearings in which the shafts and 36 are'mount-` ed are indicated bv the reference ycharacters 40 and 41, respectively.

Fixedtothe `outer ends of the crank shaft 35 is a iilv wheel 4:1",` while fixed tothe outer end of the crankshaft 36 is a pullevswheel e2, lon which trank shaft a loose `or idle pnlw ley 43 is also mounted. The crank pin 37 is mounted within a bearing at the top of a connecting rod 44, while the bearing 45 at the other end of the connecting rod is pivotally connected to the pump shaft 46. By reason of the symmetrical arrangement ofthe pump between the bearings, a simple and strong construction is produced.

For the purpose of driving the pump, Vwe provide an electric motor 47 which is mounted upon the frame 22, the drive shaft of the motor being provided with a pulley 48 which in turn drives a pulley 49 through the medium of a belt 50 trained over the two pulleys 48 and 49. A relatively small sprocket wheel 5l is keyed to the pulley 49 as at 52, so as to rotate therewith while the said sprocket and pulley are loosely mounted on the shaft 53 to which a disc 54 and a sprocket wheel 55 are fixed thereto. Journaled in the frame 22 is a shaft 56 which is disposed parallel to the shaft 53 and which shaft carries sprockets 57 and 58Y and a pulley wheel 59 all of which are fixed to said shaft. The sprocket wheel 5l drives the larger sprocket 57 by chains 60, while a belt 6l drives the shaft 53 at the required reduced speed. A relatively wide pulley 59 drives the keyed pulley 42 or idler pulley 43 by a belt 62, while an idler wheel 63 is provided for tightening` the belt to take up any slack which might be present therein. A connecting rod 65 is pivoted to the disc 54 as at 64, while the said rod is also pivoted to a rack bar 67 as at 66 and which bar is guided in its movements by suitable guides 68 and 69. The rack bar 67 meshes with a pinion 70 keyed on shaft 7l as shown in Figure 3 of the drawings.

From the description thus far it will be appreciated that the rack bar 67 will reciprocate in an up and down movement and by reason of its meshing engagement with the pinion 70 fixed on the outer end of the shaft 7l ournaled the length of the mixing tank, the said shaft 71 will be rotated alternately in opposite directions. Fixed to the shaft 7l along the length thereof and disposed within the tank are a plurality of spaced agitating paddles 72 each of which includes a plurality of radially extending blades 73 having perforations 74 therein.. These paddles 72 being iixed to the shaft 7l will rotate in opposite directions to thoroughly agitate the water within the mixing tank to fa cli tate the absorption of the carbonio gas by the water at a comparatively low pressure. The carbonio gas is fed to the mixing tank througha pipe 76 which enters the bottom of the tank as at 75. The 'opposite' end of the pipe 76 is connected to the fixture at the end of the usual carbonio tank as shown in Figure l of the drawings. lt will be appreciated that as the carbonio gas bubbles pass through the water vrising from the .bot-

tom of the tank above the surface level of the water, it further facilitates the absorpn tion of the gas by the water.

Having described the manner in which the carbonio gas is introduced into the mixing tank, we shall now proceed to explain the manner in which water is supplied thereto. The water is supplied by connecting the Water supply pipe to the connection 77 of the pump 33 as shown by the arrow 78 in Figure 3 of the drawing, while a pipe 79 leads from the outlet side of the pump 33 and is connected to a manifold or connection 80 which enters the mixing tank at 8l and 82 as best seen in Figure l of the drawings. In Figure 5 of the drawing a detail sectional View is shown of one of the water inlets 4in which a water passage or inlet 83 is provided which is covered by a tine wire mesh screen 84 seated by a threaded nipple 85 having `threaded connection with the top wall of the mixing tank. It will be evident that as the water is forced through the sieve or screen 84, it enters the interior of the mixing tank in the form of a spray and thus facilitates the further absorption of the carbonio gas by the water contained therein.

rlhe outlet from the tank for facilitating the lilling of bottles of the carbonated water is shown by the numeral 86 which represents a control cock, while mounted adjacent the tank is a pressure gage 87, a safety valve 88 being mounted in the tank as well as a water gage 89. The pressure gage of course indicates the amount of pressure within the tank, the safety valve relieves any excess pressure, while the water gage indicates the Water level within the tank.

For the purpose of automatically controlling the actuation of the pump by the water level within the mixing tank, we provide a hollow cylindrical vessel 90 which is connected at its bottom through a metal pipe 91 to an Lefitting 92 and thence to the bottom of the mixing tankby a pipe 93. The vessel 90 is fastened to one end of a lever 95 as at 94, the opposite end of the said lever having a counter balance weight 96 mountedthereon. The entire balancing system is free to turn on the axial center indicated by the reference character 97, and it will be understood that as the water within the tank rises to a given level during the actuation of the' pump 33, the water in the vessel 90 rises to the same level. W hen the water level reaches a predetermined point, the weight of the water in the vessel 90 causes the same to drop down. pushing the link 98 which is pivot/ally connected to the vertical arln of the lever and by reasonof the fact that the lever 98 is in turn connected to a second lever 99, the same tends to push a belt shifter 100 toward the right, the said belt shifter being provided with pins 102 wherebythe said belt is shifted from the fixed pulley 42-ontosthe loose or idler pulley 113, thus disconnecting the drive to the pump 33. As the carbonated.

5y and the vessel 90 drops, the said vessel becomes ghter until such time as the counter balance weight 96 overbalances the weight of the vessel whereupon thel lever is actuated in an opposite manner thusl causing the lever 99 to `actuate the belt shifter 100 in an opposite direction to slide the belt 62 onto the fixed pulley 42 to again set the pump 33 in motion. Since the vessel 90, lever 95, and pipe 91 swing on the axial center 97, the pipe 91 may be rigid or of metal, thus dise pensing with the usual practice of connecting such a vessel by the use of a flexible rubber hose. As the interior of the tank 26 andvessel 90 is filled withgas above the Zo'water level, we connect the top of the tank Y andthe vessel by a connecting flexible hose In operation of thev machine the operator l admits carbonio gas from the carbonio sup- `pipe 7 6, and the motor47 is placed in mot-ion.

If desired, an automatic pressure gage (noti shown) may be provided for admitting gasV up to a given pressure only,so as to prevent the admission of excessive pressureinto the `mixing tank. By reason of the control of the actuation of the pump by the water level in the mixing tank, the tank cannot be overiilled with water and by this feature the machine will be found to be automatic. Although the pump is thrown out of operation when the water level reaches a predetermined level in the mixing tank, the agitators 72 will continue to rotate in opposite directions to constantly agitate the water to produce a thorough mixing of the carbonic gas and the water;

While we have shown what we deem to be the most desirable embodiment of 'our invention, it is obvious that `many of the details may be varied if desired, and we do not limit ourselves to the exactl details shown and to ply tank to the mixing tank through the end thereof, a hollow vessel on the opposite end of said lever, a rigid pipev `connection between said hollow vessel and said tank, l
